Helping EVs from Overloading Grid

February 17, 2014 By Linda Hardesty

To prevent electric vehicles from overloading power grids while charging, German-based Fraunhofer is developing underlying communication methods for a uniform energy management system.

The charging station serves as an interoperable node between the electric vehicle and the network control center using the ISO/IEC 15118 and IEC 61850 standards. The requirement for EU-wide communication technologies led to the creation of the ISO/IEC 15118 standard.

“Our experience has shown that charging station manufacturers are still shying away from the standard because the implementation is too complex,” said Dr. Erik Oswald from Fraunhofer. “For this reason, we developed a reference installation that significantly streamlines the implementation.”
